Sidestream Treatment

Sidestream treatment involves specialized management of nutrient laden streams produced after anaerobic digestion of sludge and its subsequent dewatering. These streams are highly concentrated in nature, contributing only 1% to 3% of the forward flow at a wastewater treatment plant (WWTP) but comprising almost 10 to 40% of the plant’s Nitrogen and Phosphorus load. By using specialized systems geared specifically for the challenges offered by these streams, nutrient removal as well as recovery can be accomplished at the plant in a sustainable and cost effective way. The systems simultaneously proffer a host of additional benefits such freeing up mainstream treatment for increased treatment capacity as well as drastically reducing the O&M costs at the plant for a quick return on investment.
Ovivo offers the following sidestream treatment systems:
ANAMMOPAQ™ – For Nitrogen Removal in Sidestreams by deammonification
PHOSPAQ™ – For Phosphorus Removal/Recovery in Sidestreams by controlled struvite precipitation
